The south-west of Victoria will today be mostly sunny. There was patchy fog in the south-east of the region early this morning. The winds will be north to north-easterly, 25 to 35 km/h, tending north to northwesterly in the middle of the day then becoming light in the evening. Daytime maximum temperatures will be in the mid 30s. Warrnambool is expecting a top of 36 degrees, Hamilton, Colac and Portland 35 degrees. The fire danger is very high. The outlook has a high pressure system centred over the western Tasman Sea which will strengthen and move slowly eastward today as a low pressure trough moves across the Bight. The trough will enter the far west of Victoria on Friday, then will stall over northern Victoria during Saturday as a new high develops to the south of Adelaide. On Sunday the high will slip past Tasmania as the trough persists over Victoria and inland New South Wales. Top temperatures on Friday are expected to be in the mid to high 30s. Saturday will be cloudy with a 40 per cent chance of showers in the morning and afternoon. Daytime maximum temperatures are expected in the low 20s.
